Abstract: It is very important to investigate the liquid drop-solid impact to prevent material corrosion. Impacts with different diameter and different speed drops are investigated by the nonlinear coupling wave model. It is shown that the impacts with different diameter drops are similar by dimensionless process of results. Meanwhile, the effect of different impact speed is also investigated, many results as maximum dimensionless pressure, maximum dimensionless equivalent stress and the local of the maximum dimensionless equivalent stress are provided. At last, an equation describing the maximum dimensionless equivalent stress varied with Mach number is provided too.
